Ultra Heavy Cosmic Rays from Magnetars
Anirudh Patel, Rebecca Diesing, Brian Metzger
Matter ejected from the neutron star crust during a magnetar giant flare will undergo -process nucleosynthesis during decompression. Ultra heavy ions () can be acceler…
Detecting Neutrino Emission from Supernova Remnants: A Theoretically Motivated Target Catalog
Emily Simon, Rebecca Diesing, Damiano Caprioli +1
Galactic supernova remnants (SNRs) are thought to accelerate cosmic rays (CRs) to several PeV energies, but this has yet to be confirmed as general behavior. Although several sourc…
Shock Acceleration in the Intracluster Medium: Implications of Micromirror Confinement
Rebecca Diesing, Ludwig Böss, Damiano Caprioli
Merging galaxy clusters exhibit strong observational evidence for efficient particle acceleration in the intracluster medium (ICM), particularly in the form of synchrotron-emitting…
Suppression of Shock X-ray Emission in Novae from Turbulent Mixing with Cool Gas
Brian D. Metzger, Lachlan Lancaster, Rebecca Diesing
Shock interaction in classical novae occurs when a fast outflow from the white dwarf > 1000 km s/s collides with a slower, cooler shell of gas released earlier in the outburst. The…
Nonthermal Signatures of Radiative Supernova Remnants II: The Impact of Cosmic Rays and Magnetic Fields
Rebecca Diesing, Siddhartha Gupta
Near the ends of their lives, supernova remnants (SNRs) enter a "radiative phase," when efficient cooling of the postshock gas slows expansion. Understanding SNR evolution at this…
